links no longer work

Using RiscPC, RO 6.20, NS #2190, the links no longer work

To see this, load a page, eg file:///NetSurf:/Resources/en/welcome.html
and hover the pointer over a link. The pointer remains a select-arrow
and doesn't change to hand-pointing, as it should. Clicking on the link
does nothing, and the status bar remains blank.

Moving the pointer around, shows that the active location for each link
is displaced by about three lines above the link.

Does anyone else see this bizarre problem?
